Made his debut when he came on as a substitue for Edwards in a game where the Steelmen completely vanquished the Philadelphia F. C. 7-0 on March 5, 1927.
His only starting league game came on May 1, 1927 in a 6-5 loss to J & P Coats of Pawtucket. This is how the The Globe describes his debut:
"Edwards was relieved of the goal tending duties for the game against Coats and Galbraith, a newcomer to the club this season, pressed into service. The speed of the Pawtucket forward somewhat dazzled him in the opening minute of play and after eight minutes Coats had notched its third goal. From then on Bethlehem played soccer with the defense much stronger."
Galbraith later played for amongst others the IRT Rangers in the Eastern Soccer League.
